It is not only people but also the authorities..... There was an article today on Malayala Manorama regarding the same issue in cochin...... in which they spoke about 2 Bus stations, One KSRTC(old one) and the other Mobility Hub, which is used by both govt and private operators.
KSRTC one is filled with Garbage, spit, and what not, where as in the same city Mobility hub you hardly can see garbage is thrown out, and people use dustbin...... The question raised by the author was, same people use both the busstand (hardly 3 kms apart) How does people attitude changes when they get to the new busstation........ The answer is, Authorities also have a role to play....
I remember 4 or 5 years back, Railway station was filled with garbage, and people throwing garbage in the platform or in the track, but today when you see the Station is clean and you hardly can see anything on the track, and if some one even think of throwing onto track, he will retract looking at the cleanliness.....
